I just pushed a patch to deinprogramm-signature that has a custom error message for this situation:
function call: expected a function after the parenthesis, but received a signature
I'm sure it's not optimal, so happy to hear suggestions for improvement.
Thanks! This should work fine.
I would probably have used the error message rewriter to fix up the message.
Thank you for changing the error message!
Closing this one as it's been addressed.
